ABB CI627A 3BSE017457R1
Product introduction
The ABB CI627A 3BSE017457R1 is a high-reliability communication interface module designed to facilitate seamless data exchange between ABB’s AC800M controllers and field devices via PROFIBUS networks. As a key component in ABB’s industrial communication portfolio, ABB CI627A 3BSE017457R1 serves as a critical bridge between control systems and distributed field devices such as sensors, actuators, and variable frequency drives, ensuring efficient and secure data transmission in industrial automation environments.
ABB CI627A 3BSE017457R1 supports both PROFIBUS DP-V1 (for high-speed discrete and analog control) and PROFIBUS PA (for process automation in hazardous areas), making it versatile for diverse industrial applications. Its robust design, including 2 kV AC isolation and wide temperature tolerance, ensures reliable operation in harsh conditions, from chemical plants to power generation facilities. Whether integrated with digital input modules like the ABB RXIDK 2H 1MRK000838-HA or coordinating with PLCs such as the ABB PM633, ABB CI627A 3BSE017457R1 enables real-time communication, enhancing system responsiveness and operational efficiency.
Core advantages and technical highlights
Dual protocol support: ABB CI627A 3BSE017457R1 seamlessly handles both PROFIBUS DP-V1 and PA protocols, eliminating the need for separate interface modules in mixed applications. In a chemical plant, this allows the module to communicate with high-speed DP-V1 devices (e.g., motor starters) and PA field instruments (e.g., pressure transmitters in explosive zones) via a single interface, simplifying network architecture and reducing installation costs by up to 30%.
Flexible data rates: With configurable transfer speeds from 9.6 kbps to 12 Mbps, ABB CI627A 3BSE017457R1 adapts to application requirements—using lower rates for long-distance communication (up to 1200m at 9.6 kbps) and higher speeds for time-critical control (12 Mbps for distances up to 100m). In an automotive assembly line, this flexibility enables high-speed communication (12 Mbps) with robotic controllers while supporting slower, long-range links to material handling systems across the plant.
Robust isolation and noise immunity: Equipped with 2 kV AC isolation between the PROFIBUS bus and backplane, ABB CI627A 3BSE017457R1 protects sensitive control systems from electrical noise and ground loops common in industrial environments. This isolation is particularly valuable in steel mills or welding facilities, where electromagnetic interference can disrupt communication. The module’s differential signaling design further enhances noise rejection, ensuring data integrity even in noisy environments.
Seamless integration with ABB ecosystem: ABB CI627A 3BSE017457R1 is natively compatible with ABB’s AC800M controllers, PM633 PLCs, and Relion® protection relays, enabling plug-and-play configuration via ABB’s Automation Builder software. This integration reduces commissioning time by automating device discovery and parameter assignment. In a water treatment plant, for example, the module automatically recognizes connected RXIDK 2H digital input modules and configures communication parameters, minimizing setup errors.
Typical application scenarios
In a large-scale petrochemical plant, ABB CI627A 3BSE017457R1 connects an AC800M controller to a PROFIBUS PA network with 50 field instruments (pressure, temperature, and flow transmitters) in hazardous areas (ATEX Zone 1). The module’s support for PA protocols ensures safe, intrinsic safety-compliant communication, while its 12 Mbps DP-V1 interface links to 20 motor control centers, enabling real-time status monitoring and control. The CI627A’s robust design withstands the plant’s high ambient temperatures (up to 60°C) and chemical exposure, ensuring uninterrupted communication critical for process safety.
In a food and beverage production facility, ABB CI627A 3BSE017457R1 integrates with a PM633 PLC to coordinate a PROFIBUS DP network of 30 variable frequency drives (VFDs) and 15 RXIDK 2H digital input modules monitoring conveyor sensors. The module’s 9.6 kbps data rate optimizes communication with VFDs across the 500m plant floor, while its noise immunity prevents interference from washdown equipment. Operators use the ABB XVC517AE10 HMI to monitor drive speeds and conveyor status via data transmitted through the CI627A, enabling quick adjustments to production rates.
